PIN rnsrnnnn Application filed October 14, 1931 Seria1No. e',6f7-.;

My invention relatesto improvements in pin fasteners. It is particularly adapted for- Fig. 1 is a side elevation of a pin fastened" with my improved fastener to a garment.

Fig. 2 is an end view of a pin having mounted on it my improved fastener.

Fig. 3 is a central vertical sectional view of what is shown in Fig. 2, the wire of the fastener being circular in section.

Fig. 4 is a plan view of the'fastenenshown in Figs. 1, 2 and 3, having a clip thereon. Fig. 5 is a plan view of the fastener as formed from wire square in cross section.

Fig. 6 is a section on the line 6-6 of Fig. 5. Fig. 7 is a modification in which the ends of the wire abut against each other. Fig. 8 is a plan view of the clip, enlarged. Similar reference characters designate similar parts in the different views.

My improved fastener, is composed, preferably, of resilient wire of any desired cross.

5 section, as circular, as shown in Fig. 3, or square, as shown 1n Fig. 6. g

The wire 15 formed lnto a transversely divided ring- 1 from which inwardly extend two arms 2 which are respectively provided with two' arcuate portions 3 having their concave sides next to each other, and which are adapted to fit'between the threads and to embrace opposite sides respectively of a threaded shank 5 of a pin 6, as shown in Figs. 1, 2 and 3. i

The arms 2 where they merge into the ring 1 are so spaced as to be sprung away from each other when the fastener is applied transversely, as shown in Figs. 1 to 3,

'2 before the fastener is whereby the arcuate portions 3 will tightly embrace the shank 5. V I a 1 To limit such spreading, and to-increase the clamping effect of the fastener on the shank, means may-be provided for limiting 35 5. the expansion of the arms, as by a small clip 7 7, Figs. 1 and 8, or, as shown in Fig. 7, the ends of the arms 2may abut against eachv other and be fastened together, asby solder ing or welding. The clip 7 may be of any '60 suitable form and material, that shown being a plate having two holes 8, Fig. 8, through which the arms2 extend.

Such connection between the arms, as by the clip 7 or by integrally uniting the arms by soldering or Welding, serves the additional function of strengthening the fastener and reducing the liability of its becoming distorted. Z i V In applying the fastener to a pin, the, pin has its shank 5 inserted through a garment 9, as'the lapel of a coat. The shank5 is then passed between the arms 2 to a position in which the arcuate portions 3 will be disposed between the threads 4 and embrace 'ifi oppositesides of the shank, Figs. 1, 2 and 3. f When used, the clip 7 isapplied to the arms mounted on the shank5. The fastener is adapted to be usedas a substitute forthe usual nut or other thread ed'device which serves to hold the pin, and unlike such nut, it can be applied to the pin without having to be screwed -on,;and, due

to its clampingeffect, it is also adapted for V use with pins, or similar articles, having 4 smooth as well as threaded shanks. i

I do not limit my invention to the specific structure shown, as many modifications, a i 7 within the scope of the appended claims, may be made without departing from the spirit V of my invention.

What I claim is 1. A pin fastener comprising a ring having two inwardly extending resilient arms respectively provided with tWoarcuate por tions adaptedto fit between the threads and to embrace opposite sides of a threaded v shank of a pin, and a clasp adapted. to re- 110% ace leasably embrace said arms to limit their expanslon. V v 2.A pin fastener comprising a resilient I transversely divided'ring having its end I 1 portions forming inwardly extending arms
